Quick Answer
The answer is AWS Batch, because it is purpose-built for modernizing batch processing workloads while minimizing operational overhead. AWS Batch automatically provisions and manages the EC2 compute environment, launches the job when files arrive in S3, and terminates resources after completion—eliminating the need for manual cron job management or persistent instances. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of managed compute services for long-running, fault-tolerant batch jobs; a common trap is choosing AWS Lambda, which has a 15-minute timeout and cannot handle two-hour workloads, or Step Functions, which orchestrates but does not execute compute. The key distinction is that AWS Batch handles both scheduling and compute provisioning natively, whereas ECS with Fargate requires more manual configuration for job queuing and retry logic. Memory tip: think “Batch for batch” – if the job runs longer than 15 minutes and needs auto-scaling compute, AWS Batch is the direct fit.
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to modernize a batch processing application that runs on EC2 instances using a cron job. The job processes files from an S3 bucket and takes about 2 hours. They want to reduce operational overhead. Which service should they use?
AWS Batch
AWS Batch is purpose-built for batch processing and manages compute resources.
Amazon ECS with Fargate
Why wrong: Fargate can run containers but AWS Batch is simpler for batch workloads.
AWS Lambda
Why wrong: Lambda has a maximum 15-minute execution time, too short for 2-hour jobs.
AWS Step Functions
Why wrong: Step Functions is for orchestration, not compute.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Batch
AWS Batch is designed for batch computing and can automatically provision EC2 instances, run the job, and terminate them, reducing overhead. Option A (Lambda) has a 15-minute timeout. Option B (Step Functions) orchestrates but does not run the compute. Option D (ECS with Fargate) is possible but requires more configuration than AWS Batch for batch jobs.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Batch
Why this is correct
AWS Batch is purpose-built for batch processing and manages compute resources.
Related concept
Static NAT maps one inside address to one outside address.
Amazon ECS with Fargate
Why it's wrong here
Fargate can run containers but AWS Batch is simpler for batch workloads.
AWS Lambda
Why it's wrong here
Lambda has a maximum 15-minute execution time, too short for 2-hour jobs.
AWS Step Functions
Why it's wrong here
Step Functions is for orchestration, not compute.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SAP-C02 NAT questions on configuration and troubleshooting.
